Merits and requirements of a few RF architectures

In a cellular radio, as in any system, the architecture determines the quantity and quality of bipolar and BiCMOS content. Requirements and merits of a few transmitter and receiver architectures are discussed. Some of these, such as single IF, are in handsets selling by the millions every year. Some, such as direct conversion at the antenna, remain in the planning stages because of the present state of A/D technology.

BCTM, thirty years of success

Anecdotal history of BCTM during its first thirty years, written by the originator and a faithful attendee.

Human Body Model ESD Protection of RF Bipolar Circuits

RF and other high-frequency bipolar circuits operating at 1-5 GHz have been ESD protected using the human body model test to 2kV. The described design and modeling techniques minimize the operating parasitics, chip area, and number of process turn-arounds
